Collector interest
A dreamlike action adventure kept exclusive to Japan, never localised, produced within Sonic Team's orbit and carried by a soundtrack from Yoko Kanno. Its desirability stems from that rare combination: an auteur project with pastel art direction, never leaving the territory, whose score also draws followers of the composer. Quiet at launch, the title became a sought import gem, its real scarcity feeding a value that climbs as complete copies grow harder to find.
